In this talk, I’ll explore how Holland & Barrett's approach to platform engineering has evolved to support a rapidly scaling engineering organisation. As we navigated the challenges of building a resilient, user-friendly platform for nearly a thousand engineers, our focus shifted toward empowering teams through self-service tooling, enhancing observability, and embedding DevOps and SRE best practices.
We’ll discuss transitioning from traditional infrastructure management to a modern platform emphasizing scalability, cost efficiency, and high availability. I’ll share insights into the key practices and tools that have helped us create a seamless developer experience and how our open-source initiatives and SRE-driven culture have been foundational to our journey. Whether you're starting your platform engineering journey or looking to refine your approach, there will be takeaways on building a sustainable, developer-centric ecosystem at scale.
